GAS-BURNER.

Specification of Letters Patent.

Patented April 13, 1909.

Application led January 6, 1909. Serial No. 470,925.

To all whom it may concern:

Be it known that I, FRANK BUDDING- TON, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Gas- Burners, ofwhich I do declare the following to be a full, clear, and exactdescription, reference being had to the accompanying drawing, formingpart of this specification.

Figure l is a viewT in elevation of a gas burner, portions being brokenaway to show in elevation the parts inclosed within the burner casing.Fig. 2 is a view in central, vertical section through Fig. 1. Fig. 3 isa view similar to Fig. 2, but with the lower controller omitted.

This invention has for its object to pro-- vide im roved means forcontrolling the flow of uminating gas through the burner, so that a moresteady, uniform flow may be secured regardless of variations of pressureof gas under different conditions of service. This object of theinvention l have accom lished by the novel features hereinaftercescribed, illustrated in the accompanying drawing and particularlydened in the claims at the end of this specification.

Various attempts have heretofore been made to provide gas burners withcontrolling devices adapted to im rove the character of the flame and toe 'ect economy in the amount of gas consumed. To this end, it hasheretofore been proposed to provide an interior of a burner casing witha mass of mineral wool inclosed between wire gauze screens; and it hasalso been proposed to place layers of muslin or like material within thecasing of the burner in order to steady the llame of gas. Variousobjections, however, are found to exist in such prior devices. VVhere amass of mineral wool or the like is used, it has a tendency to becomeimpacted and clogged with the impurities from the gas and wheresuperposed disks of muslin or the like have been employed there is atendency of the gas to force its way through a comparatively small areaof the disks which soon become weakened and fail to effectivelydistribute uniformly the current of gas, My improved burner obviates theabove mentioned objections and provides a most simple, cheap and eectivemeans for controlling the flow of gas through the burner.

A designates the tubular body or casing of the gas burner that is shownas rovided with a metallic tip B. Beneath t e tip B I prefer to placeawire gauze screen C that aids in distributing the flow of gas andprevents possibility of any backward passage of flame from the tip.Beneath the screen C is placed my improved controller that consists of aforaminous screen D over which is stretched one or more layers oftextile fabric E. The fabric E is preferably a very thin woolen cloth orHannel, and I prefer to use two thicknesses of such fabric, as indicatedin the drawing. As shown, the foraminous screen D is cup shaped and ofslightly smaller diameter than the tubular body of the burner casing A.In applying the controller, the textile fabric is first cut intodiskshaped layers which are then placed over the foraminous screen D andthese parts are then forced upward into the casing A to a point slightlybeneath the wire screen C.

The resiliency of the cup-shaped, foraminous screen D, which ispreferably formed of wire gauze, serves to effectually bind the textilefabric E in stretched condition over the top of the screen D and betweenits edges and the wall of the inclosing casing A.

Beneath the screen D I prefer to employ a` controller such as that shownin Letters Patent No. 904,246, granted to me November 17, 1908, thiscontroller comprising an inverted cup-shaped body F having a perforationf in its bottom and a diaphragm f extending across its top, and I preferto place within this dia hragin a wire gauze screen G.

In practice, have found that by extending the layer or layers of textilefabric E over a foraminous screen D a much more uniform passage of thegas through the various parts of the textile fabric is insured, as theforaminous screen D serves not only to support the fabric in distendedcondition but aids in distributing the gas more uniformly beneath thefabric so that the fiow of gas excessively through any point of thefabric is avoided. It is obvious that, as the number of thicknesses oftextile fabric is increased the resistance offered to the flow of thegas will be correspondingly increased, but the resiliency of theforaminous screen D will permit of a variation in the number ofthicknesses of the fabric.

The term textile fabric, as herein used, I do not wish to be understoodas limited to a woven cloth since, manifestly, a thin layer 4 tendedover the top of the screen will answer the purpose, and in such easesthe screen will still perform the function of supporting and holding thetextile fabric or material and causing the flow of gas to be moreuniformly distributed therethrough.

Having thus described my invention, what I claim as new and desire tosecure by Letters PatentI is :-M

l. A controller for gas burners comprising a tubular casing, aforaminous screen Within said casing and textile material extended oversaid screen, the edges of said material being held between the screenand the wall of Y; the casing.

2. A controller for gas burners, comprising a tubular casing, acup-shaped, foraminous screen within said casing, and a layer of textilematerial extending over said casing,r and having its lower edges clampedthereto to retain said fabric in position on the screen.

a tubular casing, a foraminous screen within said casing, textile fabricextending over said screen, the edges of said fabric being held betweenthe screen and the wall of the casing, and a diaphragm located beneathsaid foraminous screen to spread the current of gas before it reachesSaid screen..
